As used throughout the present application, the terms “aryl” and“aromatic” may be understood in the broadest sense as any mono-, bi- orpolycyclic aromatic moieties. Accordingly, an aryl group contains 6 to60 aromatic ring atoms, and a heteroaryl group contains 5 to 60 aromaticring atoms, of which at least one is a heteroatom. Notwithstanding,throughout the application the number of aromatic ring atoms may begiven as subscripted number in the definition of certain substituents.In particular, the heteroaromatic ring includes one to threeheteroatoms. Again, the terms “heteroaryl” and “heteroaromatic” may beunderstood in the broadest sense as any mono-, bi- or polycyclichetero-aromatic moieties that include at least one heteroatom. Theheteroatoms may at each occurrence be the same or different and beindividually selected from the group consisting of N, O and S.Accordingly, the term “arylene” refers to a divalent substituent thatbears two binding sites to other molecular structures and therebyserving as a linker structure.

In one embodiment, the organic molecules according to the invention havean excited state lifetime of not more than 5.0 μs, of not more than 2.5μs, in particular of not more than 2.0 μs, more preferably of not morethan 1.0 μs or not more than 0.7 μs in a film of poly(methylmethacrylate) (PMMA) with 1% to 5%, in particular with 2% by weight ofthe organic molecule at room temperature.

In a further embodiment of the invention, the organic moleculesaccording to the invention have an emission peak in the visible ornearest ultraviolet range, i.e., in the range of a wavelength of from380 to 800 nm, with a full width at half maximum of less than 0.25 eV,preferably less than 0.22 eV, more preferably less than 0.18 eV, evenmore preferably less than 0.15 eV or even less than 0.12 eV in a film ofpoly(methyl methacrylate) (PMMA) with 1% to 5%, in particular with 2% byweight of organic molecule at room temperature.

Orbital and excited state energies can be determined either by means ofexperimental methods. The energy of the highest occupied molecularorbital E^(HOMO) is determined by methods known to the person skilled inthe art from cyclic voltammetry measurements with an accuracy of 0.1 eV.The energy of the lowest unoccupied molecular orbital E_(LUMO) iscalculated as E^(HOMO)+E^(gap), wherein E^(gap) is determined asfollows: For host compounds, the onset of the emission spectrum of afilm with 10% by weight of host in poly(methyl methacrylate) (PMMA) isused as E^(gap), unless stated otherwise.

The triplet energy can thus be determined as the onset of thephosphorescence spectrum. For TADF emitter molecules, the energy of thefirst excited triplet state T1 is determined from the onset of thedelayed emission spectrum at 77 K, if not otherwise stated, measured ina film of PMMA with 1% to 5%, in particular with 2% by weight of emitterand in case of the organic molecules according to the invention with 1%to 5%, in particular with 2% by weight of the organic moleculesaccording to the invention.

Furthermore, the optoelectronic device may, in one embodiment, includeone or more protective layers protecting the device from damagingexposure to harmful species in the environment including, for example,moisture, vapor and/or gases.

wherein the OLED only optionally includes each layer selected from thegroup of HIL, HTL, EBL, HBL, ETL, and EIL, and the different layers maybe merged into, one or more layers, and the OLED may include more thanone layer of each layer types defined above.

In one embodiment of the invention, the optoelectronic device is anOLED, which may have a stacked architecture. In this architecture,contrary to the typical arrangement in which the OLEDs are placed sideby side, the individual units are stacked on top of each other. Blendedlight may be generated with OLEDs exhibiting a stacked architecture, inparticular white light may be generated by stacking blue, green and redOLEDs. Furthermore, the OLED exhibiting a stacked architecture mayinclude a charge generation layer (CGL), which is typically locatedbetween two OLED subunits and typically consists of a n-doped andp-doped layer with the n-doped layer of one CGL being typically locatedcloser to the anode layer.

In particular, this so-called tandem OLED includes threeemission layers, wherein one emission layer emits red light, oneemission layer emits green light and one emission layer emits bluelight, and optionally may include further layers such as chargegeneration layers, blocking or transporting layers between theindividual emission layers. In a further embodiment, the emission layersare adjacently stacked. In a further embodiment, the tandem OLEDincludes a charge generation layer between each two emission layers.

In addition, adjacent emission layers or emission layers separated by acharge generation layer may be merged.

The substrate may be formed by any material or composition of materials.Most frequently, glass slides are used as substrates. Alternatively,thin metal layers (e.g., copper, gold, silver or aluminum films) orplastic films or slides may be used. This may allow for a higher degreeof flexibility. The anode layer A is mostly composed of materialsallowing to obtain an (essentially) transparent film. As at least one ofboth electrodes should be (essentially) transparent in order to allowlight emission from the OLED, either the anode layer A or the cathodelayer C is transparent. Preferably, the anode layer A includes a largecontent or even consists of transparent conductive oxides (TCOs). Suchanode layer A may, for example, include indium tin oxide, aluminum zincoxide, fluorine doped tin oxide, indium zinc oxide, PbO, SnO, zirconiumoxide, molybdenum oxide, vanadium oxide, tungsten oxide, graphite, dopedSi, doped Ge, doped GaAs, doped polyaniline, doped polypyrrol and/ordoped polythiophene.

The anode layer A (essentially) may consist of indium tin oxide (ITO)(e.g., (InO₃)_(0.9)(SnO₂)_(0.1)). The roughness of the anode layer Acaused by the transparent conductive oxides (TCOs) may be compensated byusing a hole injection layer (HIL). Further, the HIL may facilitate theinjection of quasi charge carriers (i.e., holes) in that the transportof the quasi charge carriers from the TCO to the hole transport layer(HTL) is facilitated. The hole injection layer (HIL) may includepoly-(3,4-ethylendioxy thiophene) (PEDOT), polystyrene sulfonate (PSS),MoO₂, V₂O₅, CuPC or CuI, in particular a mixture of PEDOT and PSS. Thehole injection layer (HIL) may also prevent the diffusion of metals fromthe anode layer A into the hole transport layer (HTL). The HIL may, forexample, include PEDOT:PSS (poly-3,4-ethylendioxy thiophene: polystyrenesulfonate), PEDOT (poly-3,4-ethylendioxy thiophene), mMTDATA(4,4′,4″-trs[phenyl(m-tolyl)amino]triphenylamine), Spiro-TAD(2,2′,7,7′-tetrakis(n,n-diphenylamino)-9,9′-spirobifluorene), DNTPD(N1,N1′-(biphenyl-4,4′-diyl)bis(N1-phenyl-N4,N4-di-m-tolylbenzene-1,4-diamine),NPB(N,N′-nis-(1-naphthalenyl)-N,N′-bis-phenyl-(1,1′-biphenyl)-4,4′-diamine),NPNPB (N,N′-diphenyl-N,N′-di-[4-(N,N-diphenyl-amino)phenyl]benzidine),MeO-TPD (N,N,N′,N′-tetrakis(4-methoxyphenyl)benzidine), HAT-CN(2,3,6,7,10,11-hexacyano-1,4,5,8,9,12-hexaazatriphenylene) and/orSpiro-NPD(N,N′-diphenyl-N,N′-bis-(1-naphthyl)-9,9′-spirobifluorene-2,7-diamine).

Adjacent to the anode layer A or hole injection layer (HIL), a holetransport layer (HTL) is typically located. Herein, any hole transportcompound may be used. For example, electron-rich heteroaromaticcompounds such as triarylamines and/or carbazoles may be used as holetransport compound. The HTL may decrease the energy barrier between theanode layer A and the light-emitting layer EML. The hole transport layer(HTL) may also be an electron blocking layer (EBL). Preferably, holetransport compounds bear comparably high energy levels of their tripletstates T1. For example, the hole transport layer (HTL) may include astar-shaped heterocycle such as tris(4-carbazoyl-9-ylphenyl)amine(TCTA), poly-TPD (poly(4-butylphenyl-diphenyl-amine)), NPD(2,2′-dimethyl-N,N′-di-[(1-naphthyl)-N,N′-diphenyl]-1,1′-biphenyl-4,4′-diamine),TAPC (4,4′-cyclohexyliden-bis[N,N-bis(4-methylphenyl)benzenamine]),2-TNATA (4,4′,4″-tris[2-naphthyl(phenyl)amino]trphenylamine), Spiro-TAD,DNTPD, NPB, NPNPB, MeO-TPD, HAT-CN and/or Tris-Pcz(9,9′-diphenyl-6-(9-phenyl-9H-carbazol-3-yl)-9H,9′H-3,3′-bicarbazole).In addition, the HTL may include a p-doped layer, which may be composedof an inorganic or organic dopant in an organic hole-transportingmatrix. Transition metal oxides such as vanadium oxide, molybdenum oxideor tungsten oxide may, for example, be used as inorganic dopant.Tetrafluorotetracyanoquinodimethane (F₄-TCNQ),copper-pentafluorobenzoate (Cu(I)pFBz) or transition metal complexesmay, for example, be used as organic dopant.

The EBL may, for example, include mCP (1,3-bis(carbazol-9-yl)benzene),TCTA, 2-TNATA, mCBP (3,3-di(9H-carbazol-9-yl)biphenyl), tris-Pcz, CzSi(9-(4-tert-Butylphenyl)-3,6-bis(triphenylsilyl)-9H-carbazole), and/orDCB (N,N′-dicarbazolyl-1,4-dimethylbenzene).

Adjacent to the hole transport layer (HTL), the light-emitting layer EMLis typically located. The light-emitting layer EML includes at least onelight emitting molecule. Particularly, the EML includes at least onelight emitting molecule according to the invention E. In one embodiment,the light-emitting layer includes only the organic molecules accordingto the invention. Typically, the EML additionally includes one or morehost materials H.

The hostmaterial H typically should be selected to exhibit first triplet (T1)and first singlet (S1) energy levels, which are energetically higherthan the first triplet (T1) and first singlet (S1) energy levels of theorganic molecule.

The OLED devicelifetime is extracted from the change of the luminance during operationat constant current density. The LT50 value corresponds to the time,where the measured luminance decreased to 50% of the initial luminance,analogously LT80 corresponds to the time point, at which the measuredluminance decreased to 80% of the initial luminance, LT 95 to the timepoint, at which the measured luminance decreased to 95% of the initialluminance etc.

Accelerated lifetime measurements are performed (e.g. applying increasedcurrent densities). For example, LT80 values at 500 cd/m² are determinedusing the following equation:

${{LT}80\left( {500\frac{{cd}^{2}}{m^{2}}} \right)} = {{LT}80\left( L_{0} \right)\left( \frac{L_{0}}{500\frac{{cd}^{2}}{m^{2}}} \right)^{1.6}}$

-   -   wherein L₀ denotes the initial luminance at the applied current        density.

The values correspond to the average of several pixels (typically two toeight), the standard deviation between these pixels is given.
